Since the computed F-ratio test statistic is greater than the F critical value. therefore location blocking is effective in reducing experimental error. Since the computed F-ratio test statistic is greater than the F

One of the reasons I've created these discussion assignments is to showcase how statistics and probability is everywhere - from exit polls during election time, experimental and observational studies, to even gambling. The following article (from March of 2019) connects expected value and the binomial theorem to something most of us have done -
